What it does

SubtleSense is an AI-powered emotion intelligence app that helps users understand not just what they show, but what they hide and suppress. Free users can do basic emotion analysis. After signing in, users unlock exclusive features: personalized moodboard, emotion timeline & graphs, a private Journal for self-reflection, weekly emotional reports, dark/light mode, and profile customization.

How we built it

Started as a web app using Lovable.dev, later converted to Android using Median.co. Core AI uses Google Gemini for multimodal analysis (facial micro-expressions + voice tone). Built with React + TypeScript, Tailwind, Supabase, and client-side processing for strong privacy.

Challenges

Debugging API errors (JSON parsing issues), low initial signup rates, and balancing development with 12th grade pressure.

What’s next

Official Android launch on May 16, 2026. After launch, focus on improving retention through the Journal and weekly reports, and exploring ways to make emotional self-awareness even more accessible.
